F101 – Contact-Molded, Fiberglass-Reinforced Plastic Wash-Water Troughs and Launders

AWWA solicits public comments on all proposed new AWWA Standards, and on all proposed revisions, reaffirmations, or withdrawals of existing AWWA Standards. The referenced standards project is being considered for approval and the publication of this notice begins the 45-day public comment period for AWWA and ANSI. An electronic public review copy of the proposed standard can be obtained for review during the comment period by emailing etssupport@awwa.org. Comments must be submitted in writing to the AWWA contact listed below no later than the last day of the comment period specified herein. Such comments shall be specific to the section(s) of the standard under review and include sufficient detail so as to enable the reader to understand the commenter's position, concerns and suggested alternative language, if appropriate.

The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal - American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal - American Water Works Association. 

SCOPE
This standard describes the minimum requirements for fiberglass-reinforced plastic wash-water troughs and launders made by the contact-molding process, including flat-bottom, round-bottom, and V-bottom troughs and launders. Requirements are included for materials, properties, design, construction, dimensions, tolerances, work quality, and appearance. This standard also describes the requirements for using general-purpose and chemical-resistant resins. These fabrications are generally used in municipal water supply service and industrial water supply service applications. 
1.1.1 Classification. Resistance to the corrosive or chemical environment shall be determined prior to molding either Type I or Type II fabrications. Typically, municipal water supply service applications use Type I, while industrial water supply service applications may use either Type I or Type II, depending on the environment. Troughs and launders shall be classified according to type as follows: 
1.1.1.1 Type I. Fabrications shall be manufactured with a polyester resin of the orthophthalic or isophthalic formulation. Type I fabrications shall be manufactured of materials suitable for general purpose applications having a temperature range not exceeding 150°F (83°C). 
1.1.1.2 Type II. Fabrications shall be manufactured with a chemical-resistant polyester resin, such as vinylester, bisphenol-A fumarate, or chlorendic formulations. Type II fabrications shall be manufactured for chemical-resistant applications having a temperature range not exceeding 200°F (111°C).
